FILTERING-FAUCET.

To all whom it may concern:

Be it known that I, LnoN DION, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Filtering- Faucets, of which the following is a specification.

This invent-ion relates to a faucet of that type in which a filtering element is contained therein so as to remove sediment, other impurities and germs from the water or liquid passing out of the faucet.

The invention has for one of its objects to improve and simplify the construction and operation of apparatus of this character so as to be comparatively simple and inexpensive to manufacture, reliable and efficient in use, of such design that the filtering element can be readily renewed by persons of ordinary skill, and composed of few parts compactly arranged so that the faucet will be of neat and attractive appearance.

Another object of the invention is the provision of a novel filtering element which has a large area exposed to the percolating water and which is fastened in place in a simple and effective manner so that renewals can be easily made.

Another object is the employment of a novel arrangement of valves whereby filtered or unfiltered water can be drawn from the faucet at will.

YVith these objects in view and others, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawings, which illustrate one embodiment of the invention, Figure 1 is a side view of a filtering faucet designed to dispense filtered or unfiltered water according to the desire of the user. Fig. 2 is a central vertical section taken longitudinally of the faucet. Fig. 3 is a perspective view of the valves removed from the casing of the faucet. Fig. 4 is a per- Specification of Letters Patent.

Serial No. 573,978.

5 and 6 are, respectively, vertical, longitudinal and transverse sections of a filtering faucet designed for use in connection with water coolers and the like. Fig. 7 is a plan view of the valve and stem of the faucet shown in Figs. 5 and 6.

Similar reference characters are employed to designate corresponding parts throughout the views.

Referring to the drawings, A designates the body or casing of the faucet which is a brass or other casting of suitable configuration, the body having a neck 1 that is adapted to be connected at 2 with the service pipe for receiving water or other liquid and at the forward part of the casing is a downwardly-extending spout or nozzle 3 through which filtered or unfiltered water can be discharged. Extending vertically across the body or casing A is a partition 4 that divides the interior of the casing into an inlet chamber 5 and a filtering chamber 6, the latter communicating with the spout through a passage 7 and the former through a passage 8 that is interrupted at an intermediate point by a cut-off valve 9. This valve is disposed in a cavity 10 formed in a boss 11 on the partition 4, and when the valve is raised or opened the water flows from the chamber 5 through part of the passage 8, cavity 10, and the other part of the passage 8., to the spout 3. The valve is opened and closed by means of a stem 12 which has an enlarged head 13 at its bottom which screws into the upper part of the cavity 10 so that by turning thestem the valve can be raised and lowered from and to its seat. On the upper end of the stem is a removable handle 14- by which the stem can be conveniently turned.

The water to be filtered passes from the chamber 5 to the chamber 6 through a port 15 in the partition 4:. This port is adapted to be closed by a valve 16 located above the valve 9 and "connected with the hub 17 of a wheel or handle 18, said hub being externally threaded to screw into an opening 19 in the top of the valve casing. The valve 16 is adapted to seat on an annular shoulder spective view of the filtering element. Figs. 20 in the casing so as to prevent water from passing through the filtering chamber. The stem 12 for the cut-off valve 9 passes axially through the valve 16 and wheel or handle 18 therefor. The valve 16 being of rubber or any other suitable material will serve as a packing around the stem 12.

The valves 9 and 16 are separately actuated so that filtered or unfiltered water can be delivered, as required. In opening the valve 9 for the unfiltered water, the handle 14 is turned so as to raise the valve and open the passage 8, the opening movement of the valve being limited by the valve 16 that forms a stop when in closed position.

When filtered water is required, the valve 9 will, of course, be closed and the valve 16 opened by turning the wheel 18 in a direction to raise the valve, and in doing this the port 15 will be uncovered so that water can pass into the filtering chamber 6. The opening movement of the valve 16 is limited by the handle 14 of the valve 9 so that each valve device acts as a stop for the other in limiting its opening movement, and in this manner the valve devices can neverbecome deranged.

The filtering chamber 9 contains a filtering element 20 which consists of a wafer of any suitable material that will intercept sediment, germs and the like, and this filtering material is inclosed between cupshaped sheets 21 of reticulated material. These sheets impart to the filtering element, which is initially in the form of a wafer, the cup shape shown, and in this manner a large area will be exposed to the water to be filtered. The plates 21 are formed with peripheral flanges 23 so that the filtering element can be effectively clamped in place against an annular shoulder 24 on the partition 4 by a cover plate 25 that closes the open front side of the filtering chamber. The cover plate sets into the chamber 6 and is clamped against the filtering element by a bolt 26 that passes through openings 27 and 28 in the cover plate and filtering element and has a threaded portion 29 which screws into a boss 30 formed on the partition 4, the winged head 31 of the bolt'bearing against the outer face of the cover plate. On the threaded portion 29 of the bolt is a nut 32 which clamps the cover plate and filtering element on the bolt before these two parts are inserted in the casing of the faucet. By assembling the parts in this man ner on the bolt in the first place permits the filtering element to be applied properly to the faucet with the least trouble to an inexperienced person. On the cover plate is an annular flange 33 which has interposed between it and the casing of the faucet a packing ring 34 so as to prevent water from leaking from the casing, and in the head 31 of the bolt 26 is a packing ring 35 which bears against the outer face of the cover plate so as to prevent leakage around the bolt.

Referring now to Figs. 5 to 7 inclusive, the faucet shown consists of a bell-shaped casing B which is open at its bottom and closed by a plate 36 that fits into the open bottom of the casing. The casing has an internal flange or shoulder 37 adjacent its bottom and clamped between this fiange and the plate 36 is the filtering element 38 which is approximately hemispherical. The plate 36 and filtering element are held in place by a clamping member or bolt 39 which passes vertically through the center of thefaucet with its upper end 40 threaded in a socket 41 on the crown of the faucet, while its lower end passes through an opening 42 in the plate 36 and terminates in a spout 43, which passage opens at 44 into the bottom of the chamber closed by the plate 36. On the lower end of the clamping bolt 39 are outwardly-extending wings 45 affording convenient means for gripping the spout by the hand in order to turn the bolt when clamping or unclamping the parts of the faucet. The clamping member 39 is formed wit-h a shoulder 46 to support the crown part of the filtering element, and the filtering element is held against the shoulder by a spring 47 inserted between the casing and filter. A packing ring 48 is set in an annular recess 49 in the spout end of the member 39, and on the plate 36 is an annular flange 50 that enters the recess 49 and bears against the packing ring so that a right joint will be formed.

The casing B is formed at its rear side with a hollow boss 51 that forms an inlet and on this boss is threaded a sleeve or connector 52 by which the faucet can be secured to a cooler in any suitable manner. The boss 51 has a conical valve seat 53 with which engages a cut-off valve 54 that is fas tened to a stem 55 extending horizontally through the valve casing and passing out through an opening 56 in the front thereof, the front end of the valve stem being provided with a push button or knob 57. There the valve stem passes out of the cas ing a packing 58 is provided to prevent leakage of water. The valve 54 is held seated'by a spring 58- arranged in the part 52 so as to press the valve inwardly. hen the push button is pressed backwardly, the stem moves the valve open against the tension of the spring 58, and when pressure is removed from the push-button the spring will re-seat the valve and cut off the water. The valve stem has its intermediate portion formed into a ring 59 so as to permit the upper end of the clampin element 39 to pass through the stem. Obviously, when the valve is opened, water enters the casing and fills the space above the filtering element 38 which is constructed like the filtering element previously described. The water percolates through the filtering element and flows out through the spout 43.
